Effect of Orange Aroma on Nausea, Vomiting and Anxiety During Autologous Stem Cell Transplantation

Earlier research indicates that aromatherapy is promising to relieve in DMSO related nausea and anxiety in autologous stem cell transplant patients. The current study seeks to confirm and extend these findings in a 2-arm, open-label randomized, controlled study of 70 cancer patients undergoing autologous stem cell transplantation. All patients will receive a standardized premedication. Arm 1: Intervention (inhalation aromatherapy with orange essential oil during stem cell infusion); Arm 2: Control (routine care). The researchers hypothesize that inhalation aromatherapy with orange essential oil will be effective in reducing DMSO related nausea and vomiting and demonstrate lower anxiety levels just after autologous stem cell transplantation.
